Aphid
Parasites
(A. matricariae) are our newest tool in the battle against aphids,
They lay their egg inside the aphid, which then develops into
a parasite larva. Before finishing development inside the aphid
egg, the larva spins a cocoon, turning the unfortunate aphid
into a leathery "mummy". The adult parasite then flies
out from a circular hole cut in the mummy.
For
preventative control small releases will get these established,
repeat regularly through the season. These are used in European
greenhouses, but are new here. Supplied near hatching, or as
adults (no choice).
